If you need to set up and use MFA with EmailMeForm, there are plenty of options for apps that you can use, no matter what platform you are on. EmailMeForm’s Multi Factor Authentication uses a widely accepted industry standard called TOTP (Time-based One Time Passwords) which is compatible and interoperable between all platforms.
Options are a bit more limited for this platform. We recommend using Microsoft’s own Authenticator app.
The option we can recommend here is using Authy Windows app.
We recommend using Authy MacOS app.
We recommend using Oathtool: a command line tool for generating and validating OTPs.
